Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to an improved structure of a cultivating section cover that covers the outside of the rotary range of a pawl shaft rotary in a cultivating section mounted on a cultivator.

[0002]

[Prior art]

 Conventionally, the tiller cover that covers the outside of the rotary range of the pawl shaft rotary of the tiller mounted on the tiller is called the front half cover that covers the part from the front surface of the pawl shaft rotary to the upper front half. , The rear half cover that covers the part from the upper half to the rear of the rotary shaft of the pawl is divided and the front half of the two covers is fixed to the power tiller frame such as a transmission case. The rear half of the front half of the cover is hinged so that the latter half of the cover can be opened upward, and resistance rods, which are depth gauges, are installed on the left and right sides of the latter half of the cover. It has been known that it is attached to a wide side plate (see, for example, Japanese Utility Model Laid-Open No. 61-100908).

[0003]

[Problems to be solved by the device]

 In the conventional type, the rear half cover is pivotally opened upward under the posture in which the pawl shaft rotary is supported by the ground contact between the traveling wheels on the tiller side and the depth gauge on the tiller side. Although it is possible to locally expose the upper half of the claw shaft rotary to the rear side of the claw shaft rotary, there are wide upper and lower side plates on both left and right sides of the exposed part. Since the part from the front surface of the shaft rotary to the upper front half is covered with the front half cover, these are the desorption of the plowing pawl or the plowing shaft cylinder of the pawl shaft rotary and the pawl shaft rotation. There was a problem that it was difficult to perform maintenance because the space for performing maintenance such as removal of mud adhering to the tarry and the cultivated area cover was restricted.

Therefore, the present invention does not stably support the pawl shaft rotary by grounding the traveling wheels on the cultivator side and the depth gauge on the cultivator side, which are located in front of and behind the pawl shaft rotary. However, the present invention provides a covering structure of a tillage part, which allows the nail shaft rotary to be exposed almost all over the surface so that maintenance can be performed very easily.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, in the present invention, a tiller unit having a transmission case having a lower end supporting a pawl shaft rotary and a main beam connected to the transmission case. In a cultivating section for a cultivator in which a cultivating section cover for covering the outside of the rotary range of the pawl shaft rotary is provided in a frame, a depth gauge is installed in the cultivating section machine frame and the cultivating section cover Is formed by integrally connecting side covers to the left and right ends of the upper cover that covers the upper part of the rotary shaft of the claw shaft rotary, and the tiller cover is used as a fulcrum at one end in the front-rear direction. It has a tiller cover structure that is attached to the tiller machine frame so that it can be opened upward.

[0006] Further, a tilling part cover attached to the tilling part machine frame so as to be opened upward with one end side in the front-rear direction as a fulcrum is superposed on an upper side of a receiving plate part provided on the tiller part machine frame side. The one-tatch stopper is used to fix the claw shaft rotary to maintain the posture so as to cover the outside of the gyroscope.

[0007]

[Effect of the invention]

 According to the cultivating section cover structure of the present invention, the pawl shaft rotary is stably supported by the traveling wheels on the cultivating side and the depth gauges on the cultivating section side which are located in front of and behind the pawl shaft rotary. The tiller cover can be rotated upward with one end in the front-rear direction as a fulcrum to open substantially the entire circumference of the claw shaft rotary, and as a result, the tiller claw of the claw shaft rotary can be opened. Alternatively, it is possible to easily carry out maintenance such as detachment of the tillage shaft cylinder and removal of mud adhering to the claw shaft rotary and the tillage part cover.

[0008] The depth gauge and the main beam, which is a part of the cultivating section machine frame, are kept in the same range, and only the relatively lightweight cultivating section cover is rotated to move around the claw shaft rotary. Since it is opened, the operation load for opening and closing movement is light and the load on the opening and closing fulcrum of the tillage cover is small, which is advantageous in terms of strength. Also, the tiller cover that opens and closes with one end in the front-rear direction as a fulcrum is superimposed on the upper side of the receiving plate provided on the tiller machine frame side, and fixed with a one-touch stopper to fix the pawl shaft rotary. By configuring so as to maintain the posture that covers the outside of the rotasphere, the opening and closing operation becomes easier to perform, and the tilling part cover in the cover posture is maintained reliably and firmly.
